Your answer is partially correct. On January 2, Macaron Ltd. sold merchandise on account to R. Thomas for $51,000, terms n/30. The company uses a perpetual inventory system and the merchandise originally cost $30,500. On February 1, R. Thomas gave Macaron a five-month, 6% note in settlement of this account. Interest is due at the beginning of each month, starting March 1. On April 30, Macaron's year end, annual adjusting entries were made. On July 1, R. Thomas paid the note and any remaining interest.
